LDAP+Kerberos - JDK-8149521 also in JDK9

[Bill Mair]

Hi,

Am I posting this to the correct list? If I am, would someone please
tell me who to send this information to?

I would like to confirm that this bug still indeed exists, as Balchandra
Vaidya requested.

From what I can see error hasn't been fixed in jdk9 either:

http://hg.openjdk.java.net/jdk9/jdk9/jdk/file/f38c0650a60f/src/java.naming/share/classes/com/sun/jndi/ldap/ServiceLocator.java

Thanks and regards,

    Bill Mair

Hi,

I've just ran in to the same problem described in this bug: https://bugs.openjdk.java.net/browse/JDK-8149521

I found it in java7u79 and I used java8u91 to confirm it still exists.

The error is in "com.sun.jndi.ldap.ServiceLocator" at line 273 (http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/df209f221cca/src/share/classes/com/sun/jndi/ldap/ServiceLocator.java),

The "Hostname" token always has a trailing "." (period). This doesn't normally matter for "normal" network operation but it is critical where working with Kerberos.

If you use "ldap:///dc=example,dc=com" the the corresponding name might be something like "ldap1.example.com."(notice the trailing dot)

Kerberos is then looking for "ldap/ldap1.example.com." instead of "ldap/ldap1.example.com"

The first record simply doesn't exist in the kerberos DB.

Regards,
